Tree health survey

September 23, 2013

The OPAL tree health survey – only three weeks left survey closes end of September. The survey is best carried out when leaves are still on the trees and signs of pests and diseases are easier to spot.

The Open Air Laboratories (OPAL) network is open to anyone with an interest in nature. The survey was developed by OPAL in partnership with Forest Research and Fera, and is taking place across England, Scotland and Wales.
